• Q: How to service and repair the wiper motor on 2007 Scion tC?

  A: A necessary first step for wiper motor repair includes disconnecting the battery cable from the negative terminal followed by a minimum 90-second wait before continuing to avoid Air Bags and seat belt pretensioner activation. The first step requires removal of front wiper arm head caps before uninstalling the front wiper arm and blade assemblies starting with the left-hand side assembly by removing the nut followed by removing the right-hand side assembly in the same way. The removal of the cowl top hood to seal demands 8 clip detachment followed by disconnection of 5 claws together with 2 clips to extract the cowl top ventilator louver LH. First remove the 4 bolts while disconnecting the connector to extract the windshield wiper motor and link assembly. The procedure includes disconnecting the wiper link rod with a taped-up screwdriver from the windshield wiper motor while rotating the motor crank arm to the required position then unfastening the 3 bolts to remove the wiper motor. Begin the installation of the windshield wiper motor by securing its 3 bolts with 5.4 N.m (55 kgf.cm, 47 in.lbf) torque then position the crank arm according to specifications before applying DENSO No.50 grease to the crank arm pivot followed by attaching the rod onto the wiper link. Proceed to install the 4 bolts of the windshield wiper motor and link assembly at 5.4 N.m (55 kgf.cm, 47 in.lbf) torque level before reconnecting the connector. The windshield installation requires attachment of 5 claws, 2 clips for the cowl top ventilator louver LH and 8 clips for the hood to cowl top seal. Clean the wiper arm serrations together with the wiper pivot serration before installing the front wiper arm and blade assembly LH with its nut placed at the correct spot using a torque of 34.3 N.m (350 kgf.cm, 25 ft.lbf) while manually tightening the arm hinge to fasten the nut. Complete the second installation phase of the front wiper arm and blade assembly RH according to the technical specifications by securing the nut at 34.3 N.m (350 kgf.cm, 25 in.lbf) but also maintain manual contact with the arm hinge. After reattaching the negative battery wire complete the system initialization since it requires post-cable-disconnect procedures.
